the trick to using a kurt vise is , when you want to cut step jaws clamp on a parallel directly below where you are going to cut the step , to compensate for the lift ,this way you are assured acurracy when you clamp down on your part the lift shouldn t be an issue , and if you keep a consistant clamp pressure between parts you should aquire a fairly consistant parallism
keep the set screw snug ,because when you are clamping with hard jaws the fixed jaw will be square to the bottom of the vise , the moving jaw however will lift and no longer be parallel to the other jaw especially when you are clamping high in the vise , this will cause your part not to have even clamping pressure and the jaws will have a tendancy to push the part out , and even more so as you apply more pressure
kurt vises are bullet proof , after a while you ll be glad you didn t buy imports
next time look at CHICK vises dont let the price or the aluminum scare you , they work the opposite the more pressure the more the jaw sucks down , they don t lift , and in my opinion they are the best  |
